3 Claims.

.This invention relates to an improvement in bufling material packages, and particularly to a glue, water and abrasive compound which is applied to the surface of a bufling wheel, such as loose cotton bufi, bristle circular brush, wire circular brush, etc., to produce an abrading surface. This abrasive material in solid bar form is sensitive to the drying action of the atmosphere, and it is desirable thatthe container be waterproof.

The object of this invention is to provide a waterproof container with provision for removing portions of the said container as the contents are used, and the invention consists in the constructionas hereinafter described and. particularly recited in the claims. Y

In the accompanying drawing: Fig. 1 is a side view of a container for bufling material in solid bar form, constructed in accordance with my invention;

Fig. 2 is a side view, partly in section, on a larger scale, showing the container filled but with the cap removed;

Fig. 3 is a perspective view, partly broken away, illustrating the cap to be applied to the open end of the container;

Fig. 4 is a sectional view of theopen end of the container, showing the closure-cap applied thereto, Fig. 4 being on a larger scale than Fig. 2; and

Fig. 5 is a side view showing the upper end of the container tom away to expose the contents.

In carrying out my invention, I employ a tubular casing 6 formed from very thin metal, similar to that commonly used in collapsible tubes. This casing is drawn up from a disk of 7 metal, forming a comparatively thick conical top l with a closed center 8. The other end of the container is formed with an outw rdly-extending flange 9. v

After the container has been filled with bufling material, a cap I is placed over the open end, this cap being formed with an inset central portion adapted to enter the open end of the container, and with a lip I I adapted to permanently interlock with the flange 9 and form an air-tight seal. This cap is formed from metal of a thickness to prevent the collapsing of the closed end of the tube, and by projecting into the tube, ilrmly (organs-e) holds the end of the container in its round shape.

house, the top 1 is cut away, which may be readily done with the point of a knife or other sharp device, exposing the tapered end of the 5 contents of the container, and this exposed end is pressed against a buifing wheel so as to transfer the contents of the container to the wheel. As the contents of the container are worn away, the open end of the container is torn off, which may 10 be readily done with the fingers, so as to expose the material for application to a bufling wheel, and this tearing away is continued until the contents of the container are exhausted.

When not in use, the exposed end of the material may be readilygcovered with any suitable means, so as to prevent exposure to the atmosphere. a

I claim:

1. Anew article of ufacture comprising: an air-tight metal container including a casing; and a bar of water-containing solid bufling material filling said casing; said casing consisting of an elongated, transversely and longitudinally continuously integral side-wall and a top-end 5 cap, said casing being preformed to its final shape and size independently of said bar of bufiing material, said side-wall'being composed of metal the nature .of which is such that portions thereof can be successively readily torn away with the fingers to expose an end of the bar of bufling material as the latter is consumed.

2. A new article of manufacture comprising: an air-tight metal container including a casing; a bar of water-containing solid bufiim material filling said casing; said casing consisting of a cylindrical, transversely and-longitudinally continuously integral side-wall and a top-end cap, said casing being preformed to its finalshape and size independently of said bar of bufling material, said side-wall being composed of metal the nature of which is such that portions thereof can be successively readily torn away with the fingers to expose an end of the bar of bufiing material as the latter is consumed; I and theother end of said casing being permanently closed by an annular metal bottom-end cap.

' 3. A new article of manufacture comprising: an air-tight metal container including a casing;

2 v p 2,018,076 a bar of water-containing solid bumngr material filling said casing; said casing consisting of an elongated, transversely and longitudinally continuously integral side-wall and a top-end cap, said'casing being preformed to its final shape and size independently of said bar of bufllng material, said side-wall being composed of metal the nature of which is such that portions thereof can be successively readily torn away with the. fingers to expose an end of the bar of bufilng material as the latter is consumed; and the other end of said casing being permanently closed by a metal bottom-end cap; said topand bottom-end caps being substantially thicker than said side-wall.
